How do spiders build webs in zero gravity? (dmns.org)
On earth, orb weaving spiders rely on gravity cues and wind currents to construct their webs and to position themselves in the silken orb. (dmns.org)
One of the unique challenges was building a habitat that allowed spiders access to food and water while also providing an unobstructed view of the webs. (dmns.org)
Cameras took pictures of the habitats and colleagues Samuel Zschokke of the University of Basel, Countryman and Cushing analyzed the symmetry of webs and the orientation of spiders. (dmns.org)
One intriguing discovery was that it made a difference whether the spiders began building their webs when lights set in the top of the habitat were on or when the lights were off and the habitat was dark. (dmns.org)
If the spiders began building their webs during the dark cycle of the experiment, the webs were more symmetrical and the spiders rested in random orientations in the webs. (dmns.org)
If web construction began when the lights were on, the webs were as asymmetrical as the terrestrial webs and the spiders tended to orient facing down. (dmns.org)
These rare, fist-sized spiders do not make webs, but rather excrete secretions which harden upon contact with air. (strolen.com)
These are particularly numerous in hunting or wandering spiders which do not build webs to catch prey but roam around and much more rely on their tactile sense than do for instance orb weavers. (scholarpedia.org)
